If this is keeping me awake, I'll move to tell her to roll over, and she'll stop before I even say anything. So I'll lay back down. And she'll start again. So I'll move to tell her to roll over. And she'll stop. Before I say anything.
Some nights this goes on for quite a while. Most nights I tell her to roll over anyway.
But it's interesting to me that, even in her sleep, my wife is messing with me.
